Description

Technical Field

[0001] The invention relates to the technical field of workpiece processing, in particular to a wire cutting processing method, a positioning module, a fixture and a processing method. Background Art

[0002] Wire cutting workpiece processing, due to the long processing time of wire cutting, generally adopt the production method of processing multiple workpieces at the same time to improve the production efficiency of workpieces. However, some workpieces (see Figure 1 ) Due to the limitation of the structural shape, there are sharp angles or points with the supporting part of the fixture. At this time, there is a problem of tip discharge. Since the fixture is made of metal material to ensure hardness, wear resistance and high precision requirements, tip discharge will corrode the positioning surface of the fixture, causing the fixture to lose its most important positioning function, thereby failing to meet the processing accuracy of the workpiece and causing the fixture to be scrapped, resulting in economic losses.

[0003] In order to achieve the requirements of simultaneous processing, positioning and fixing of multiple workpieces, the current wire cutting fixtures require the precise coordination of multiple parts to achieve accurate fixing and positioning of the workpieces, thereby ensuring the processing accuracy of the workpieces. However, due to the large number of parts for positioning and fixing the workpieces, and the high precision requirements for installation, it is inconvenient to disassemble the various parts of the fixture, and it is difficult to restore them after disassembly. Moreover, after wear, they can only be returned to the manufacturer for overhaul or scrapping and replacement, which is costly. Moreover, when processing workpieces with sharp edges, the tip discharge effect will cause corrosion to the fixture positioning surface, thereby accelerating the wear of the fixture, shortening the life of the fixture, increasing the cost of use, and making large-scale production and processing impossible.

[0004] Therefore, there is an urgent need for a wire cutting processing method, a positioning module, a fixture and a processing method that can reduce processing costs, reduce operating difficulty and improve processing accuracy. Summary of the invention

[0005] The present application provides a wire cutting processing method, a positioning module, a fixture and a processing method, which can reduce processing costs, reduce operating difficulty and improve processing accuracy.

[0006] The first aspect of the present application provides a wire cutting processing method for performing wire cutting processing on a workpiece, wherein the workpiece has a clamping end and a processing end, and the clamping end has a tip; the method comprises: a workpiece installation step, wherein the clamping end of the workpiece is embedded in a fixing portion at one side edge of a positioning module, wherein the positioning module comprises: a main body, wherein the main body is a plate-like component, and has two parallel clamping surfaces, and the size of the main body in the thickness direction is adapted to the workpiece; a fixing portion, wherein the fixing portion is in the shape of a notch, and is arranged at the edge of the main body, connecting the two clamping surfaces, and the fixing portion is adapted to the shape of the clamping end, and after the clamping end is embedded in the fixing portion, the tip contacts the bottom surface of the notch of the fixing portion; the fixing portion is arranged on at least two sides of the main body On the edge, there are multiple fixing parts on the same side edge, and the multiple fixing parts are arranged in a straight line, so that after the multiple fixing parts are respectively installed in the clamping end of the workpiece, the processing paths of the processing end overlap when viewed along the arrangement direction of the fixing parts; placing the positioning module between the two jaws of the vise, controlling the vise to make the two jaws close to each other, respectively abutting against the two clamping surfaces and the clamping end, so that the processing end is exposed from between the two jaws; controlling the cutting line to process the processing end along the processing path of the processing end, so that tip discharge is generated between the tip and the bottom surface of the notch of the fixing part; removing the workpiece; checking the wear state of the bottom surface of the fixing part; when the wear state of the fixing part cannot meet the precision requirement of workpiece processing, replacing a new positioning module.

[0007] From the above, the clamping end of the workpiece can be embedded in the fixing part, and the fixing part fixes the workpiece so that the workpiece can only move in the direction corresponding to the two clamping surfaces. Then, the two clamping surfaces and the clamping end can be clamped and fixed by the two jaws of the vise, so that the fixing of multiple workpieces can be achieved, so that the processing paths of the processing ends of multiple workpieces overlap, so as to perform wire cutting processing on the processing ends of multiple workpieces at the same time. Therefore, only one component of the positioning module can be prepared to cooperate with the vise to achieve the fixing of the workpiece, thereby reducing the number of components required for fixing the workpiece to reduce the manufacturing cost. The number of components that need to be operated when fixing the workpiece can also be reduced. When the positioning module is corroded due to the tip discharge effect of the workpiece and the positioning module needs to be replaced, the difficulty of operation can be reduced, and the positioning module can be replaced more conveniently and quickly. Moreover, since the number of components that need to be operated when fixing the workpiece is reduced, the vise only needs to provide sufficient clamping force to achieve the clamping and fixing of the positioning module and the workpiece, which can not only improve the firmness and stability of the workpiece during processing, but also reduce the accuracy difference generated when the components cooperate, thereby improving the positioning accuracy of the workpiece and improving the processing accuracy of the workpiece.

[0008] As a possible implementation of the first aspect, the main body is square, and the fixing portion is arranged on at least two side edges of the main body; it also includes: checking the wear state of the fixing portion; when the wear state of the fixing portion on one side edge of the main body cannot meet the precision requirement of workpiece processing, before replacing a new positioning module, the clamping end of the workpiece is embedded in the fixing portion on the other side edge of the main body.

[0009] As described above, when the fixing part on one side of the main body cannot meet the machining accuracy requirement of the workpiece due to wear, it is not necessary to directly replace the positioning module, and the workpiece can be fixed by the fixing part on the other side of the main body. In this way, the service life of the positioning module can be increased and the loss cost of the positioning module can be reduced.

[0010] The second aspect of the present application provides a wire cutting positioning module, which cooperates with a vise to fix the clamping end of a workpiece so as to process the processing end of the workpiece, and the clamping end has a pointed end; the positioning module includes: a main body, which is a plate-like component and has two parallel clamping surfaces; a fixing part, which is in the shape of a notch and is arranged on one side edge of the main body to connect the two clamping surfaces, and the fixing part is adapted to the shape of the clamping end, and after the clamping end is embedded in the fixing part, the pointed end is arranged toward the inner circumferential surface of the fixing part; there are multiple fixing parts, and the multiple fixing parts are arranged in a straight line, so that after the multiple fixing parts are respectively installed in the clamping ends of the workpiece, the processing paths of the processing ends overlap when viewed along the arrangement direction of the fixing parts.

[0011] From the above, the clamping end of the workpiece can be embedded in the fixing part, and the fixing part fixes the workpiece so that the workpiece can only move in the direction corresponding to the two clamping surfaces. Then, the two clamping surfaces and the clamping end can be clamped and fixed by the two jaws of the vise, so that the fixing of multiple workpieces can be achieved, so that the processing paths of the processing ends of multiple workpieces overlap, so as to perform wire cutting processing on the processing ends of multiple workpieces at the same time. Therefore, only one component of the positioning module can be prepared to cooperate with the vise to achieve the fixing of the workpiece, thereby reducing the number of components required for fixing the workpiece to reduce the manufacturing cost. The number of components that need to be operated when fixing the workpiece can also be reduced. When the positioning module is corroded due to the tip discharge effect of the workpiece and the positioning module needs to be replaced, the difficulty of operation can be reduced, and the positioning module can be replaced more conveniently and quickly. Moreover, since the number of components that need to be operated when fixing the workpiece is reduced, the vise only needs to provide sufficient clamping force to achieve the clamping and fixing of the positioning module and the workpiece, which can not only improve the firmness and stability of the workpiece during processing, but also reduce the accuracy difference generated when the components cooperate, thereby improving the positioning accuracy of the workpiece and improving the processing accuracy of the workpiece.

[0012] As a possible implementation manner of the second aspect, the main body is square, and the fixing portion is arranged on at least one side edge of the main body.

[0013] As described above, by arranging the fixing part on at least one side edge of the main body, when the fixing part on one side edge cannot be used due to wear or corrosion caused by the tip discharge effect of the workpiece, the fixing part on the other side edge can be replaced to fix the workpiece. In this way, the service life of the positioning module can be improved and the loss cost of the positioning module can be reduced.

[0014] As a possible implementation of the second aspect, the two jaws of the vise are close to and separated on the base of the vise, and a stopper is provided on one side between the two jaws; the two side edges connected to the main body are respectively used to abut against the base and the stopper.

[0015] As described above, the two adjacent sides of the main body are respectively attached to the base and the stopper, so that the positioning module can be positioned. Thus, the position accuracy of the positioning module and the workpiece can be improved, and the difficulty of operating the positioning module to fix the workpiece can be reduced.

[0016] As a possible implementation of the second aspect, the length of the main body is set so that one side edge of the main body abuts against the stop block, and after the two jaws respectively abut against the two clamping surfaces, one side edge of the fixing part of the main body is located at a corresponding position of the edge on the other side of the two jaws.

[0017] From the above, by setting the edge of one side of the fixing part of the main body to be located at the corresponding position of the edge of the other side of the two jaws, after the positioning module is positioned by the base and the stop block, the two jaws can clamp and fix the clamping end in the fixing part, and the processing end can also be exposed between the two jaws to facilitate wire cutting of the processing end using a cutting wire.

[0018] As a possible implementation manner of the second aspect, a dimension of the main body in a thickness direction is smaller than that of the workpiece, and specifically, may be, for example, 0.1 mm smaller.

[0019] From the above, by making the size of the main body smaller than the workpiece in the thickness direction, the two jaws of the vise can be used to clamp the clamping end, which can not only improve the clamping force on the clamping end, but also provide protection for the workpiece to avoid excessive clamping force that causes deformation of the clamping end and affects the processing accuracy. By making the size of the main body 0.1mm smaller than the workpiece in the thickness direction, when the clamping end is slightly deformed under the action of the clamping force, the two clamping surfaces of the main body abut against the two jaws, so that the vise can directly clamp and fix the clamping end, thereby improving the firmness and stability of the workpiece and improving the processing accuracy of the workpiece.

[0020] A third aspect of the present application provides a wire cutting fixture, comprising a vise and a positioning module, wherein the vise has two jaws that can be brought close together and separated, and the positioning module is the positioning module described in any one of the second aspects of the present application; the vise and the positioning module cooperate to fix the clamping end of the workpiece so as to process the processing end of the workpiece.

[0021] From the above, the clamping end of the workpiece can be embedded in the fixing part, and the fixing part fixes the workpiece so that the workpiece can only move in the direction corresponding to the two clamping surfaces. Then, the two clamping surfaces and the clamping end can be clamped and fixed by the two jaws of the vise, so that the fixing of multiple workpieces can be achieved, so that the processing paths of the processing ends of multiple workpieces overlap, so as to perform wire cutting processing on the processing ends of multiple workpieces at the same time. Therefore, only one component of the positioning module can be prepared to cooperate with the vise to achieve the fixing of the workpiece, thereby reducing the number of components required for fixing the workpiece to reduce the manufacturing cost. The number of components that need to be operated when fixing the workpiece can also be reduced. When the positioning module is corroded due to the tip discharge effect of the workpiece and the positioning module needs to be replaced, the difficulty of operation can be reduced, and the positioning module can be replaced more conveniently and quickly. Moreover, since the number of components that need to be operated when fixing the workpiece is reduced, the vise only needs to provide sufficient clamping force to achieve the clamping and fixing of the positioning module and the workpiece, which can not only improve the firmness and stability of the workpiece during processing, but also reduce the accuracy difference generated when the components cooperate, thereby improving the positioning accuracy of the workpiece and improving the processing accuracy of the workpiece.

[0022] The fourth aspect of the present application provides a positioning module processing method, wherein the positioning module is the positioning module described in any one of the second aspect of the present application, comprising: selecting a plate as a main body, the size of the plate in the thickness direction is adapted to the workpiece, and the parallel two side surfaces of the plate form two clamping surfaces of the main body; processing a notch connecting the two clamping surfaces on the edge of the main body to form a fixing portion, the fixing portion is adapted to the shape of the clamping end of the workpiece, and a plurality of the fixing portions are provided, and the plurality of the fixing portions are arranged in a straight line, so that after the plurality of the fixing portions are respectively installed in the clamping ends of the workpiece, the processing paths of the processing ends overlap when viewed along the arrangement direction of the fixing portions.

[0023] As described above, by processing the fixing portion on the edge of the plate to fix the workpiece, workers can use local materials to make the positioning module, thereby reducing the processing difficulty of the positioning module and reducing the loss cost of the positioning module.

[0024] These and other aspects of the invention will become apparent from the following description of the embodiment(s). BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Below, in conjunction with the accompanying drawings, a possible embodiment of the wire cutting positioning module 200 in the present application is exemplarily described.

[0042] Figure 2 It is a schematic diagram of the orthographic projection structure of one side of the clamping surface 211 of the positioning module 200 in Embodiment 1 of the present application; Figure 3 for Figure 2 A schematic diagram of the orthographic projection structure of one side of the fixing portion 220 is provided; Figure 4 This is a schematic diagram of the side orthographic projection structure of the clamp 10 in Example 1 of the present application; Figure 5 for Figure 4 Sectional view in the AA direction; Figure 6 for Figure 4 A schematic structural diagram of the two jaws 120, 130 of the middle vise 100 in a separated state.

[0043] like Figure 2-Figure 6As shown, the present application provides a wire cutting positioning module 200, which cooperates with the vise 100 to fix the clamping end 21 of the workpiece 20 so as to process the processing end 22 of the workpiece 20, and the clamping end 21 has a pointed end; the positioning module 200 includes: a main body 210, the main body 210 is a plate-like component, and has two parallel clamping surfaces 211; a fixing part 220, the fixing part 220 is in the shape of a notch, and is arranged on one side edge of the main body 210, connecting the two clamping surfaces 211, the fixing part 220 is adapted to the shape of the clamping end 21, and after the clamping end 21 is embedded in the fixing part 220, the pointed end is arranged toward the inner circumferential surface of the fixing part 220; a plurality of fixing parts 220 are provided, and the plurality of fixing parts 220 are arranged in a straight line, so that after the plurality of fixing parts 220 are respectively loaded into the clamping ends 21 of the workpiece 20, the processing paths of the processing end 22 overlap when viewed along the arrangement direction of the fixing parts 220.

[0044] From the above, the clamping end 21 of the workpiece 20 can be embedded in the fixing part 220, and the fixing part 220 fixes the workpiece 20 so that the workpiece 20 can only move in the direction corresponding to the two clamping surfaces 211. Then, the two clamping surfaces 211 and the clamping end 21 can be clamped and fixed by the two jaws 120 and 130 of the vise 100, so that multiple workpieces 20 can be fixed, so that the processing paths of the processing ends 22 of multiple workpieces 20 overlap, so as to perform wire cutting processing on the processing ends 22 of multiple workpieces 20 at the same time. Therefore, only one component of the positioning module 200 can be prepared to cooperate with the vise 100 to fix the workpiece 20, so as to reduce the number of components required to fix the workpiece 20 and reduce the manufacturing cost. It can also reduce the number of components that need to be operated when fixing the workpiece 20. When the positioning module 200 is corroded due to the tip discharge effect of the workpiece 20 and needs to be replaced, the difficulty of operation can be reduced. The positioning module 200 can be replaced more conveniently and quickly. Moreover, since the number of parts that need to be operated when fixing the workpiece 20 is reduced, the vise 100 only needs to provide sufficient clamping force to clamp and fix the positioning module 200 and the workpiece 20. This can not only improve the firmness and stability of the workpiece 20 during processing, but also reduce the accuracy difference caused by the cooperation between the various parts, thereby improving the positioning accuracy of the workpiece 20 and improving the processing accuracy of the workpiece 20.

[0045] In some embodiments, Figure 2 , Figure 5 As shown, the main body 210 is square. Specifically, it can be square or as Figure 2 The fixing portion 220 is arranged on at least one side edge of the main body 210. Specifically, it can be arranged on one side edge of the main body 210. Figure 2As shown, the fixing parts 220 are arranged at positions corresponding to the two short sides of the main body 210. It can also be arranged on the four side edges of the main body 210, and there is no limitation on this. Thus, by arranging the fixing part 220 on at least one side edge of the main body 210, when the fixing part 220 on one side edge cannot be used due to wear or corrosion caused by the tip discharge effect of the workpiece 20, the fixing part 220 on the other side edge can be replaced to fix the workpiece 20. Thus, the service life of the positioning module 200 can be improved, and the loss cost of the positioning module 200 can be reduced.

[0046] In some embodiments, Figure 5 , Figure 6 As shown, the two jaws 120 and 130 of the vise 100 are close to and separated on the base 110 of the vise 100, and a stopper 150 is provided at one side between the two jaws 120 and 130. The two sides connected to the main body 210 are respectively used to abut against the base 110 and the stopper 150. Thus, the two adjacent sides of the main body 210 are respectively abutted against the base 110 and the stopper 150, so that the positioning module 200 can be positioned. Thus, the position accuracy of the positioning module 200 and the workpiece 20 can be improved, and the difficulty of operating the positioning module 200 to fix the workpiece 20 can be reduced.

[0047] In some embodiments, the length of the main body 210 is set such that, after the edge of one side of the main body 210 abuts against the stopper 150 and the two jaws 120 and 130 respectively abut against the two clamping surfaces 211, the edge of one side of the fixing portion 220 provided on the main body 210 is located at the corresponding position of the edge of the other side of the two jaws 120 and 130. Thus, by making the edge of one side of the fixing portion 220 provided on the main body 210 be located at the corresponding position of the edge of the other side of the two jaws 120 and 130, after the positioning module 200 is positioned by the base 110 and the stopper 150, the two jaws 120 and 130 can clamp and fix the clamping end 21 in the fixing portion 220, and the processing end 22 can be exposed between the two jaws 120 and 130, so as to facilitate the wire cutting of the processing end 22 using the cutting wire.

[0048] In some embodiments, the size of the main body 210 in the thickness direction is smaller than that of the workpiece 20, specifically, it can be, for example, 0.1 mm smaller. Therefore, by making the size of the main body 210 in the thickness direction smaller than that of the workpiece 20, the clamping force of the two jaws 120, 130 of the vise 100 on the clamping end 21 can be improved, and the workpiece 20 can be protected to avoid deformation of the clamping end 21 due to excessive clamping force, thereby affecting the processing accuracy. By making the size of the main body 210 in the thickness direction smaller than that of the workpiece 20 by 0.1 mm, when the clamping end 21 is slightly deformed under the action of the clamping force, the two clamping surfaces 211 of the main body 210 are in contact with the two jaws 120, 130, so that the vise 100 can directly clamp and fix the clamping end 21, thereby improving the firmness and stability of the workpiece 20 and improving the processing accuracy of the workpiece 20.

[0049] The present application also provides a clamp 10. The specific structure of the clamp 10 in the present application is described in detail in a specific embodiment below in conjunction with the accompanying drawings.

[0050] Example 1

[0051] like Figure 4 , Figure 6 As shown, the clamp 10 in the present application includes a vise 100 and a positioning module 200, and the vise 100 and the positioning module 200 cooperate to Figure 1 The clamping end 21 of the workpiece 20 shown in the figure is fixed so that the processing end 22 of the workpiece 20 can be processed by a wire cutting tool. The vise 100 includes a base 110, a first jaw 120, a second jaw 130, an adjusting wrench 140 and a stopper 150. The upper surface of the base 110 is provided with a horizontal working surface 111, and the first jaw 120 is fixed on the upper surface of the base 110 and is located at one end of the working surface 111. The second jaw 130 is arranged on the working surface 111 and is slidably connected to the working surface 111. The adjusting wrench 140 is arranged on the base 110 and is transmission-connected with the second jaw 130. By rotating the adjusting wrench 140, the second jaw 130 can be driven to move toward the first jaw 120, so that the second jaw 130 is close to the first jaw 120. The second jaw 130 can also be driven to move away from the first jaw 120, so that the second jaw 130 is away from the first jaw 120. The stopper 150 is fixed to the first jaw 120 by means of bolts and is located at a side position between the first jaw 120 and the second jaw 130 .

[0052] like Figure 2 , Figure 3 , Figure 5As shown, the positioning module 200 includes a main body 210 and a fixing part 220. The main body 210 is a rectangular plate-like component, and two clamping surfaces 211 are formed on the parallel surfaces on both sides of the main body 210. A plurality of fixing parts 220 in the shape of rectangular notches are formed at the edge positions corresponding to the two short sides of the main body 210, so that the plurality of fixing parts 220 on both sides of the main body 210 are arranged in a straight line along the corresponding short sides of the main body 210. The shape of the fixing part 220 is adapted to the shape of the clamping end 21 of the workpiece 20, so that the clamping end 21 can be embedded in the fixing part 220, and the fixing part 220 fixes the workpiece 20 on the plane where the main body 210 is located. At the same time, the processing end 22 of the workpiece 20 can be exposed from the main body 210 so that the cutting line can cut the processing end 22.

[0053] Depend on Figure 1 As shown, the clamping end 21 of the workpiece 20 is rectangular in shape, and the processing end 22 is tilted at one end of the clamping end 21. When the processing end 22 of the workpiece 20 is subjected to wire cutting along the processing path, the cutting line needs to maintain an inclined state with the clamping end 21.

[0054] like Figure 2 , Figure 5 As shown, the fixing part 220 and the short side of the main body 210 are tilted at a certain angle, so that the processing paths of the processing ends 22 of the workpieces 20 in the multiple fixing parts 220 overlap along the extension direction of the short side of the main body 210. Therefore, when the processing ends 22 are subjected to wire cutting, the cutting line can be parallel to the short side of the main body 210, so that when the cutting line moves along the processing path, the processing ends 22 of multiple workpieces 20 can be subjected to wire cutting at the same time.

[0055] When the fixture 10 of this embodiment is used to fix the workpiece 20, the workpiece 20 is first embedded in the multiple fixing parts 220 on the short side of the main body 210, and then the positioning module 200 is placed between the first jaw 120 and the second jaw 130, so that the short side of the main body 210 where the workpiece 20 is not installed is in contact with the stopper 150, and the lower edge of the main body 210 is in contact with the working surface 111. The adjusting wrench 140 is operated to move the second jaw 130 toward the first jaw 120, so that the positioning module 200 and the workpiece 20 are clamped and fixed.

[0056] Specifically, the length of the main body 210 is adapted to the width of the first jaw 120 and the second jaw 130, that is, after the short side of the main body 210 on which the workpiece 20 is not installed is in contact with the stopper 150, the short side of the workpiece 20 installed is located at the corresponding edge position of the first jaw 120 and the second jaw 130, so that the first jaw 120 and the second jaw 130 can only clamp and fix the clamping end 21 in the fixing portion 220, so that the processing end 22 of the workpiece 20 is exposed between the first jaw 120 and the second jaw 130, so as to facilitate the use of the cutting line to process the workpiece 20. The width of the main body 210 is adapted to the height of the first jaw 120 and the second jaw 130, that is, after the lower edge of the main body 210 is in contact with the working surface 111, the upper edge of the main body 210 is flush with the upper edges of the first jaw 120 and the second jaw 130. After the clamping end 21 of the workpiece 20 is embedded in the fixing portion 220, the main body 210 is 0.1 mm thicker than the workpiece 20 in the thickness direction, so that the first jaw 120 and the second jaw 130 can firstly abut against the clamping end 21 when clamping, thereby improving the clamping force and further improving the stability of clamping the workpiece 20. It is also possible to make the first jaw 120 and the second jaw 130 abut against the two clamping surfaces 211 respectively when the clamping end 21 of the workpiece 20 is slightly deformed, thereby preventing the clamping end 21 from deforming too much under the action of the clamping force and affecting the processing accuracy of the workpiece 20. In addition, the clamping end 21 of the workpiece 20 is clamped and fixed on both sides corresponding to the two clamping surfaces 211 by the first jaw 120 and the second jaw 130, so that the workpiece 20 can be fixed in a direction perpendicular to the two clamping surfaces 211. In this way, the workpiece 20 can be fixed in multiple directions in cooperation with the fixing portion 220.

[0058] Figure 7 FIG. 2 is a schematic diagram of the orthographic projection structure of one side of the clamping surface 211 of the positioning module 200 in Embodiment 2 of the present application. Figure 7 As shown, the present application also provides another positioning module 200. Compared with the positioning module 200 in Example 1, the difference is that the shape of the fixing portion 220 in the positioning module 200 in Example 2 is different from the shape of the fixing portion 220 in Example 1. Specifically, the shape of the clamping end 21 of the workpiece 20 to be fixed by the positioning module 200 in Example 2 is a special-shaped shape, and accordingly, the shape of the fixing portion 220 in the positioning module 200 is also a special-shaped shape. For other technical features of the positioning module 200 in Example 2, please refer to the relevant content in Example 1, which will not be repeated here. The present application also provides a positioning module processing method 30 for processing the positioning module 200 in the above-mentioned embodiment. Below, in conjunction with the accompanying drawings, the specific steps of the positioning module processing method 30 in the present application are described in detail.

[0059] Figure 8 FIG. 3 is a flow chart of the positioning module processing method 30 in this application. Figure 8 As shown, the specific steps of the positioning module processing method 30 in the present application include:

[0060] Step S310: Select a suitable plate.

[0061] In step S310, a suitable plate is selected as the main body 210, and the size of the plate in the thickness direction should be compatible with the size of the workpiece 20. Specifically, the size of the plate in the thickness direction is 0.1 mm smaller than the size of the workpiece 20. The two parallel side surfaces of the plate are used as the two clamping surfaces 211 of the main body 210, thereby reducing the processing amount and the processing difficulty.

[0062] Step S320 , performing the first processing on the main body 210 .

[0063] In step S320, the main body 210 is processed for the first time, and the main body 210 is processed into a rectangle of appropriate size. Specifically, the length of the main body 210 after processing is set so that after one short side of the main body 210 is in contact with the stopper 150, the other short side is located at the corresponding position of the edge of the first jaw 120 and the second jaw 130. The width of the main body 210 after processing is set so that after one long side of the main body 210 is in contact with the working surface 111, the other long side is located at the corresponding position of the upper edge of the first jaw 120 and the second jaw 130.

[0064] Step S330 , performing a second processing on the main body 210 .

[0065] In step S330, the main body 210 is processed for the second time, and a notch-shaped fixing portion 220 is processed on the main body 210. Specifically, the fixing portion 220 is located at the edge position corresponding to the two short sides of the main body 210, and a plurality of fixing portions 220 are evenly arranged along the extension direction of the short sides. The shape of the fixing portion 220 is the same as the shape of the clamping end 21 of the workpiece 20, and the clamping end 21 of the workpiece 20 can be embedded in the fixing portion 220, so that the processing end 22 of the workpiece 20 is exposed from the main body 210.

[0066] The present application also provides a clamp using method 40, which uses the clamp 10 in the above embodiment to fix the workpiece 20. The specific steps of the clamp 10 method in the present application are described in detail below in conjunction with the accompanying drawings.

[0067] Fig. 9 FIG. 4 is a flow chart of the wire cutting method 40 in the present application. Fig. 9 As shown, the specific steps of the wire cutting processing method 40 in the present application include:

[0068] Step S410 , installing the workpiece (blank) 20 .

[0069] In step S410 , the clamping end 21 of the workpiece 20 is embedded into the fixing portion 220 at one side edge of the main body 210 , and the fixing portion 220 limits the workpiece 20 so that the workpiece 20 cannot move on the plane where the main body 210 is located.

[0070] Step S420 : fix the positioning module 200 .

[0071] In step S420, the positioning module 200 is placed between the two jaws 120, 130 (the first jaw 120 and the second jaw 130) of the vise 100, so that the short side of the main body 210 on which the workpiece 20 is not installed is in contact with the stopper 150 of the vise 100, and the lower edge of the main body 210 is in contact with the working surface 111 of the vise 100. In this way, the positioning module 200 can be positioned by the stopper 150 and the working surface 111, so that the fixing portion 220 and the clamping end 21 are located at corresponding positions between the two jaws 120, 130, and the processing end 22 is exposed between the two jaws 120, 130. The adjusting wrench 140 is rotated to move the second jaw 130 toward the first jaw 120 and respectively contact the two clamping surfaces 211 of the main body 210, so that the positioning module 200 and the clamping end 21 of the workpiece 20 are clamped and fixed between the two jaws 120 and 130, so that the workpiece 20 cannot move in the direction perpendicular to the clamping surface 211. In this way, the positioning module 200 and the workpiece 20 can be fixed, and the processing end 22 can be conveniently processed.

[0072] Step S430 , processing the processing end 22 .

[0073] In step S430 , the processing end 22 of the workpiece 20 is processed using a wire cutting tool.

[0074] Step S440 , disassembling the workpiece 20 .

[0075] In step S440, the adjusting wrench 140 is rotated to move the second jaw 130 away from the first jaw 120, so as to remove the positioning module 200. After the positioning module 200 is removed, the workpiece 20 embedded in the fixing portion 220 is removed.

[0076] Step S450 : inspect the fixing portion 220 .

[0077] In step S450, the fixing part 220 on which the workpiece 20 has been installed is checked. When the wear condition of the fixing part 220 can meet the processing requirements of the workpiece 20, the process returns to step S410 to fix and process the next batch of workpieces 20. When the fixing part 220 on one side edge of the main body 210 cannot meet the processing requirements of the workpiece 20 due to tip discharge and wear, the process proceeds to step S460. When the fixing parts 220 on all side edges of the main body 210 cannot meet the processing requirements of the workpiece 20 due to tip discharge and wear, the process proceeds to step S470.

[0078] Step S460: Replace the fixing portion 220.

[0079] In step S460, the clamping end 21 of the workpiece 20 is embedded in the fixing portion 220 at the other edge of the main body 210, and the fixing portion 220 at the other side limits the workpiece 20 so that the workpiece 20 cannot move on the plane where the main body 210 is located. Finally, step S420 is entered.

[0080] Step S470 , replace the positioning module 200 .

[0081] In step S470, a new positioning module 200 is replaced, and the clamping end 21 of the workpiece 20 is embedded in the fixing portion 220 at one side edge of the main body 210 of the new positioning module 200. The fixing portion 220 limits the workpiece 20 so that the workpiece 20 cannot move on the plane where the main body 210 is located. Finally, step S420 is entered.

[0082] With the present invention, the fixture has only one special part, namely the positioning module. The positioning module is simple to manufacture and low in cost. Parts can be installed on both sides and have a long service life. Once worn, it can be quickly replaced. It is particularly suitable for large-scale production and processing of parts with pointed discharge. At the same time, from the perspective of workers' operation, the quick-change wire cutting fixture is simple and quick to install / remove parts, which improves production efficiency and reduces the difficulty of workers' operation. The quick-change wire cutting fixture can be quickly replaced due to low cost, and the positioning surface can be kept in a consistent and effective state during the production process. It will not be worn out like ordinary fixtures and cannot be replaced, thereby improving the quality of the product. The fixture is suitable for different types of parts. It only needs to modify the card slot to meet the processing of parts with different shapes and meet the diversity of usage scenarios.

[0083] By adopting the above-mentioned implementation mode, the following technical effects can be obtained: 1. The fixture has only one special part, the positioning module, which is simple to manufacture and low in cost. The positioning module can be quickly loaded and unloaded and replaced, and the positioning module can be replaced by itself according to the degree of wear and the shape of the processed parts. It is suitable for processing parts with large wear on the fixture and different shapes. 2. The fixture relies on a universal vise to fix the parts, eliminating the need for designing and manufacturing a large number of parts. 3. The fixture is simple and convenient to operate, and is very operator-friendly. 4. The cost of using the fixture is low, which reduces the production cost and overcomes the problem of high fixture loss cost of tip discharge parts. 5. The fixture relies on the cooperation of the movable vise and the positioning module to achieve 5 degrees of freedom restriction on the parts. The part positioning accuracy is high, and each dimension is well guaranteed, thereby ensuring the processing quality of the parts.

[0084] In addition, when clamping, there is no need to tighten the screws of each pressure plate by hand, only the wrench of the vise needs to be tightened, which is convenient, simple and quick. The fixture can be quickly loaded and unloaded, which is convenient for workers to replace worn fixtures. The positioning module is small in weight and volume and has a low manufacturing cost. There is only one special part, which reduces the design, manufacturing and use costs of the entire fixture. When processing parts with sharp edges, the positioning surface of the fixture will be corroded due to the tip discharge effect, but the fixture positioning module can be quickly replaced at a very low cost, which enables large-scale production and processing of parts using this fixture. The fixture has achieved 5 degrees of freedom restrictions on the parts, the positioning accuracy of the parts is high, and the dimensions are well guaranteed to ensure the processing quality of the parts.
